Data from: Native freshwater species get out of the way: Prussian carp (Carassius gibelio) impacts both fish and benthic invertebrate communities in North America
Prussian Carp (Carassius gibelio) are one of the most noxious non-native species in Eurasia. Recently, Prussian Carp, a non-native freshwater fish species, were genetically confirmed in Alberta, Canada and have been rapidly expanding their range in North America since establishment. Given their rapid range expansion, there is an increasing need to determine how Prussian Carp may impact native species. We assessed the severity of the Prussian Carp invasion by 1) determining their impact on fish communities, 2) assessing their impact on benthic invertebrate communities, 3) evaluating if Prussian Carp alter abiotic conditions, and 4) identifying where we find higher abundances of Prussian Carp. When Prussian Carp were established, we found significant changes to the fish community. Correspondingly, the degree of impact to benthic invertebrate communities was related to the stage of invasion (none, early, or recent), where changes in fish communities were significantly concordant with changes in benthic invertebrate communities. Finally, we found that higher abundances of Prussian Carp were significantly associated with lower abundances of a majority of native fish species. Altogether, using three lines of evidence, we determine that Prussian Carp can have wide ranging impacts on freshwater ecosystems in North America, pressing the need for management intervention.

Figure 4 in Invasive Carassius spp. in the Tiber River basin (Umbria, Central Italy): population status and possible interactions with native fish species
Figure 4. – Canonical Correspondence Analysis: plot of the densities of native and non-native species. The eigenvalues of axes 1 and 2 were 0.249 and 0.046, respectively. The first two axes explained 73.70% of the total variance.

Figure 3. – Canonical Correspondence Analysis plot of the environmental variables. The arrows represent the vectors of the environmental variables. The length of the arrow is proportional to the importance of each variable: a long arrow indicates large spatial changes closely correlated with the ordination axes.
